← ScienceWhich outcome occurs when a magnetic field collapses around a shorted transformer winding?
A)Rapid current increase in the winding✓
B)Increased core saturation and hysteresis
C)Reduction of coil's parasitic capacitance
D)Enhanced mutual inductance with other phases
💡 Explanation
A collapsing magnetic field induces a voltage because of Faraday's law of induction, therefore a shorted winding will experience a rapid surge of current, rather than changes in core properties or capacitance because the short creates a low-resistance path, drastically impeding usual field effects.
